000 AXPZ20 KNHC 032023 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat Apr 3 2021 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2015 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: North to northeast gale- force winds in the Gulf of Tehuantepec, with winds to 35 to 40 kt evident on morning scatterometer data, will slowly diminish through tonight, becoming minimal gale force early Sun, then diminishing to below gale force by Sun afternoon. Wave heights will remain 11-15 ft through this evening. Swell generated by these winds will spread well to the west- southwest of the Gulf of Tehuantepec region this weekend. Mariners are urged to use caution due to the hazardous marine conditions. Please read the latest HIGH SEAS FORECAST- https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N80W to 05N87W to 04N97W. The ITCZ continues from 04N97W to 03N120W to beyond 02N140W. Scattered moderate convection is noted from 03N to 05N between 117W and 126W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details on gale-force winds in the Gulf of Tehuantepec region. The pressure gradient supports moderate to locally fresh northwest to north winds west of Baja California. High pressure building west of Baja California will tighten the gradient, with these winds increasing to fresh to locally strong through early next week. Elsewhere, light to gentle winds are noted. Wave heights are generally 5 to 6 ft in mixed southwest and northwest swell. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Strong east-northeast winds are in the Gulf of Papagayo region. Wave heights in the Papagayo region are in 8-10 ft range, in a mix of northeast and southwest swell. Moderate winds have developed in and downwind of the Gulf of Panama today. Light to gentle winds and 4 to 7 ft seas prevail elsewhere across the region. Strong offshore northeast gap winds will continue across in Papagayo region into Mon. Large seas will continue west of Central America, from northern Costa Rica to Guatemala, from swell generated in the Tehuantepec and Papagayo source areas into Monday. REMAINDER OF THE AREA... High pressure of 1023 mb is analyzed near 30N127W. The resultant gradient between the high and lower pressures in the tropics is supporting fresh northeast to east trade winds from 07N to 17N west of 110W. Wave heights within this area are around 8 ft in mixed north to northwest and southerly swell. Little change is expected through the weekend over this part of the discussion area. In the far NW waters, a low pressure system is expected to meander north of 30N and west of 140W for several days, and drag a weak cold front into the area tonight and Sun. The front is expected to stall and weaken over the far NW waters, but seas generated by this low pressure system are forecast to build to the 8-12 ft range Sun through Mon, with highest seas expected in the far NW part of the area. $$ KONARIK
